I think so. We have glorified and deified people to the extent that we are unable to learn actual history about them. No historical figure should be off-limits to criticism, and I find it strange that so people are offended by criticism of people who aren’t alive, who they never met. So offended by reality and education.

Regardless, there’s a difference between people who owned slaves (kind of, anyway) and people who were willing to die themselves and leave the country over their right to continue a practice that was being made illegal worldwide, that was being heavily debated. By time the Civil War rolled around, abolitionism was a mainstream ethical movement and frankly, only really unethical people (or really rich people) were still promoting it and rounding up support for their cause by saying “the north wants to take away your rights.”
